Solution

The correct option is C 0.0
$y = t a n^{- 1} (\frac{l o g_{e} (e / x^{2})}{l o g_{e} (e x^{2})}) + t a n^{- 1} (\frac{3 + 2 l o g_{e} x}{1 - 6 l o g_{e} x}) = t a n^{- 1} (\frac{1 - 2 l o g_{e} x}{1 + 2 l o g_{e} x}) + t a n^{- 1} (\frac{3 + 2 l o g_{e} x}{1 - 3.2 l o g_{e} x}) = t a n^{- 1} (1) - t a n^{- 2} (2 l o g_{e} x) + t a n^{- 1} (3) + t a n^{- 1} (2 l o g_{e} x) = t a n^{- 1} (1) + t a n^{- 1} (3) \frac{d y}{d x} = 0$
